How much does a 170-190 lb passenger and windows rolled down effect 1/4 time?

 

passenger alone is close to about two tenths.No idea on windows down though.

 

windows down = wind drag! It will impare your ET a bit.
Every 100lbs = a 10th of a second.

wow..... i had a passenger in my truck that weighed about 220 lbs and windows down. and lost by a truck at 90mph vs a 05 silverado(toyo's K&N and superchips).

 

wow, didn't know it was that big of a difference on the weight factor. I need to lose some weight hahaha

 

first of all, they don't let you run the 1/4 mi with your windows down
rule of thumb, every 100lbs. shed off will net you 1/10 drop in et.

 

this was on street though. was just wonderin how much it hurts the quickness n stuff

 

I looked it up once, and I think that my crew cab is about 800 lbs. heavier than an RCSB. I'll probably still give it a try at the track, just for the hell of it.

Drop the spare, take the tailgate and tool box off and I could probably shed 200 lbs. pretty easily. If you're really trying to lose the weight with easily reversable mods, lose the jack and passenger seats too.

Don't forget to fold the mirrors in too!

 

I see people pulling in their mirrors, but I seriously doubt there is much of a difference with them out.

Yeah, I was half joking there. I guess I needed one of these
